Application filed January 25, 1911. Serial No. 604,621.

To all whom it may concern Be it known that I, JOSEPH L. HILLER, acitizen of the United States, residing at Mattapoisett, in the county ofPlymouth and State of Massachusetts, have invented new and usefulImprovements in Bearings, of which the following is a specification.

My invention consists of an improved bearing of the ring oiling ball andsocket type, particularly adapted for use in connection withmachinesdoing heavy work at high speed, and for use under unfavorable workingconditions Where careless attendance prevails.

Tn ball and socket bearings of the oil ring type heretofore made,trouble has been had with the bearings of large size owing to inabilityto properly handle the oil rings with out moving the shaft from thebearings or vice versa when it was desired to take out an oil ring orother parts of the bearings. In many large machines it is impracticableto move the shaft from the bearings, the bearings from the shaft, or tojack theshaft out of line. In cases Where it is practicable much time islost. Attempts have been made to adapt the bearings to these conditionsbut in many instances the result has been impaired lubrication,decreased bearing surface, and strength, and a more orless openstructure which admits dust and foreign matter to the bearings. One ofthe chief reasons for these difficulties and disadvantages has been thelack of sufficient space for manipulation and lubrication.

The aim of my invention is to produce a.

bearing adapted especially for heavy use in which all of thesedifficulties are avoided, and disadvantageous features eliminated, thebearing while admitting ready manipulation of its parts giving atthe'same time perfect lubrication.

In the accompanying drawings, I have shown one embodiment of myinvention.

Of the drawings Figure 1 is a side elevation of the bearing and itssupport. Fig. 2 is a longitudinal vertical section of the same showingthe shaft in place in the bearing; Fig. 3 is a transverse sectionthrough the center of the bearing on line 3--3 of Fig. 2, Fig. 4 is atransverse section on line la of Fig. 2 showing the parts in theirnormal opcrating positions, Fig. 5 is a transverse sec tion on the sameline eti showing the parts n a posltlon in which the rings may beremoved prior to the removal of a liner, and

Fig. 6 is a top plan view of the lower cap or half of the bearing.

The body of the bearing 10 is composed of two halves 11 and 12. Thesehalves of the bearing are provided respectively with ball low block 18.The bearing proper 10 is of considerably greater length than the cap andpillow block are wide, the ends of the bearing projecting a considerabledistance on each side of the support 18. As is usual in bearingsof thistype the cap 17 and block 18 are bolted together. By virtue of the balland socket, thebody of the bearing may move with respect to the supportin response to abnormal strain and normal flexing of the shaft.

Instead of making the radius of the sphericalsurfaces 13 and 14 of thebearings of the same radius as is usual, I form the surface 14 of thelower half of the bearing on a larger radius, but nevertheless form thesurfaces concentric with each. other. The lower half 12 of the body ofthe bearing 1 make correspondingly larger, the enlargement being madeparticularly in depth as is clearlv shown in Fig. 3.

Within the body of the bearing, the bearing surface is formed by ribs 19on the member 12, and 20 on the member 11. These ribs are castintegrally with the members 11 and 12 respectively, and the ribs 19 passacross the body 12 above the bottom, being connected to the body only attheir ends. The ribs of the upper half are babbitted as clearly shownfor contact with the shaft. The ribs 19 of the lower half are notbabbitted, but are machined for bearing a liner 21 placed between themand the shaft, and which in turn is babbitted for properly bearing theshaft. This liner is of a length equal to the distancebetween theoutside ends of the end most ribs. The adjacent edges of the lower halfof the bearing, and the liner are beveled or chamfered on arcs ofcircles as shown, this chamfering being done throughout the length ofthe liner on each side. Beyond the ends of the liner are provided spaces22 and 23, the space 22 being somewhat larger thanthef' space 23'. Thesespaces are formedby interiorly enlarging the members 11 and 12, theenlargement 0]": the member-'l2 extending welljd'own" into the depth ofthe member. A solid oil ring is placed around theshaft in each spacebetweentwo adjacent ribs 19 and 20. Thesd rings are of such diameterthatwhen they" rest on top of the shaft they hangat the bottom Well downbelow the ribs l9 of the lower half ofthe bearing. 7

The tWo halvesyll a'nd'12 ofthe. hearing are bolted-together bybo-lts".- On the abuttingfaces ofthe halves 11- and-12 are 7 formed oilgrooves 26 (see-Fig 6 and Figi The oil grooves 26*015 the uppier' andlower halves 11- ahd 12 1'egister .-and the ends of the grooves adjacentthe bolts 25' are turned ini'vardlyand enter the interior of'thebearing.

' bottommost position, by engagement of its upper edges with the loweredges of the ribs of the upper half 11 of the bearing. Furthermore, alsothe body of the hearing as a 1 whole is prevented from rotating in thesocket formed by the support 18 and cap 17 by reason of the fact thatits edges 57 of the lower half project laterally beyond the edges of theupper half 11. These laterally projecting edges are engaged by the lowerfaces of the cap 17, and rotation of the bearing thus cannot take place.For all of these facts however, the bearingis free to move about theball and socket as a center there being no hindrance to this movementsince both spherical ball surfaces 13 and 14, are formed from the samecenter which center is on the axis line of the shaft, through which axisthe plane of division of the halves 11 and 12 of the bearing passes.

'In order to prevent possible interference from the lower faces of thecap 17, the top surfaces 38, of member 12, are sloped downwardly andoutwardly from a central line,

this slope preferably taking the form of the plane as shown. There isthus no interference when oscillation of the bearing takes place in avertical plane. The laterally projecting portions 37* of the lower half12 of the bearing might be so curved instead of the lower faces of thecap 17.

While I have described the best form of my invention now known to me, Idesire to have it understood that any modifications may be made withoutdeparting from its generic spirit. I desire to cover all suchmodifications in the annexed claims.
